The Astrophysical Journal, 1993 A study is conducted of cold dark matter (CDM) models in which clumpiness will inhere, using cosmic strings and textures suited to galaxy formation. CDM clumps of 10 million solar mass/cu pc density are generated at about z(eq) redshift, with a sizable fraction surviving.

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications
Advanced Functional Materials, EarlyView.Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Cold Quad‐Modal Nanocomplex for Precise and Quantitative In Vivo Stem Cell Tracking
Advanced Functional Materials, EarlyView.Multimodal albumin–bismuth sulfide–superparamagnetic iron oxide (ABS) nanocomplexes are developed for stem cell tracking across four different imaging modalities: MRI, MPI, MSOT, and CT. Combining its flexibility with high sensitivity, this quad‐modal imaging agent enables a robust quantification of ABS‐labeled stem cells in vivo.

Advanced Functional Materials, EarlyView.A transparent, laser‐microscribed glass platform enables cancer diagnosis within 1 h—much faster than histology, which takes days, and free from the chemical or contrast risks of MRI or CT scans. The antibody‐functionalized rough glass surface captures viable cancer cells directly from suspension, allowing instant optical readout and offering a rapid ...

Advanced Healthcare Materials, EarlyView.Molecule 2, which contains a shorter oligoether chain, binds to tamoxifen via structural similarity forming micelles with a positive surface charge, thereby enhancing cellular uptake. These fluorescent micelles induce lipid droplet (LD) accumulation, exhibit strong fluorescence, and effectively overcome tamoxifen resistance by synergizing with orlistat‐

Advanced Healthcare Materials, EarlyView.This work presents a “tooth‐on‐chip” device that mimics dental pulp tissue. By co‐culturing key cell types, it recreates vascular networks, stem cell niches, the odontoblast/dentine interface, and trigeminal innervation. This innovative platform provides a unique model of dental pulp structure and physiology, with significant potential for accelerating
